North American Bat Monitoring Program (NABat) Integrated Summer Species Distribution Model: Predicted Tricolored Bat Occupancy Probabilities

September 1, 2023

These data contain the results from the North American Bat Monitoring Program's (NABat) integrated species distribution model (iSDM) for tricolored bats (Perimyotis subflavus). The provided tabular data include predictions (with uncertainty) for tricolored bat occupancy probabilities (i.e., probability of presence) based on data from the entire summer season (May 1–Aug 31), averaged from 2017-2022, in each NABat grid cell (5km x 5km scale) across the range of the species. Specifically, predictions represent occupancy probabilities in the pre-volancy season in the summer (May 1 – July 15), i.e., the period of time before juveniles can fly and become detectable. Predictions were produced using an analytical pipeline supported by web-based infrastructure, Bayesian hierarchical modeling, and iSDM framework which integrated stationary acoustic, mobile transect acoustic), and live-capture data to model the recent summer distribution of the species while accounting for imperfect detection and species misclassification. A tabular file is included detailing the average occupancy probability predictions (from 2017-2022) of each 5 km x 5 km grid cell in the species range, including means, standard deviations, and the 95% Bayesian credible intervals. These data can be cross-referenced to the NABat CONUS 5km master sample for analytical or visualization purposes.
